Volvo 740 Stalls - Electrical Goes Out, Then Comes Back
I own a 1990 Volvo 740 Base GL Sedan 4D 2.3L l4 MPI, Assembled in Sweden. It has around 70k miles on it.
I have been having a very weird stalling issue with this car. The car stalls mainly when making a fair right turn soon after the car has been started. It stalls, and all of the electrical goes out. 2-3 minutes later, the electrical comes back, and the car runs just like nothing happened. It otherwise drives like a dream.
I've replaced the fuel pump relay twice, and both the radio suppression relays. I've tested them and they work just fine.
It almost seems like there is a built in kill switch that triggers from the inertia of the vehicle turning; like it has a crash detector that shuts everything off in case of an accident.
Any ideas? Would appreciate any and all help!

Strange! With 70k miles, if correct, this car should be pristine; no worn out ignition switch for sure... Is the battery securely tied down? On Some models the battery slides and shuts off the motor by touching some relay attached on the fender but that's rare. That was on Turbos anyway...

the correct volvo batteries have a flange on the bottom and are 'clamped' to the battery tray, either a screw clamp or a slider clamp depending on the model and year. but a lot of crappy places will just sell you a generic battery that doesn't have the flange, and you end up having to use a nylon battery strap to keep it secure.
